After dying a laughable and pathetic death on his way back from buying a game, high school student and recluse Kazuma Satou finds himself sitting before a beautiful but obnoxious goddess named Aqua. She provides the NEET with two options: continue on to heaven or reincarnate in every gamer's dream—a real fantasy world! Choosing to start a new life, Kazuma is quickly tasked with defeating a Demon King who is terrorizing villages. But before he goes, he can choose one item of any kind to aid him in his quest, and the future hero selects Aqua. But Kazuma has made a grave mistake—Aqua is completely useless! Unfortunately, their troubles don't end here; it turns out that living in such a world is far different from how it plays out in a game. Instead of going on a thrilling adventure, the duo must first work to pay for their living expenses. Indeed, their misfortunes have only just begun!

When Kazuma Satou died, he was given two choices: pass on to heaven or be revived in a fantasy world. After choosing the new world, the goddess Aqua tasked him with defeating the Demon King, and let him choose any weapon to aid him. Unfortunately, Kazuma chose to bring Aqua herself and has regretted the decision ever since then. Not only is he stuck with a useless deity turned party archpriest, the pair also has to make enough money for living expenses. To add to their problems, their group continued to grow as more problematic adventurers joined their ranks. Their token spellcaster, Megumin, is an explosion magic specialist who can only cast one spell once per day and refuses to learn anything else. There is also their stalwart crusader, Lalatina Ford Darkness Dustiness, a helpless masochist who makes Kazuma look pure in comparison. Kono Subarashii Sekai ni Shukufuku wo! 2 continues to follow Kazuma and the rest of his party through countless more adventures as they struggle to earn money and have to deal with one another's problematic personalities. However, things rarely go as planned, and they are often sidetracked by their own idiotic tendencies.

Asta and Yuno were abandoned at the same church on the same day. Raised together as children, they came to know of the Wizard King—a title given to the strongest mage in the kingdom—and promised that they would compete against each other for the position of the next Wizard King. However, as they grew up, the stark difference between them became evident. While Yuno is able to wield magic with amazing power and control, Asta cannot use magic at all and desperately tries to awaken his powers by training physically. When they reach the age of 15, Yuno is bestowed a spectacular Grimoire with a four-leaf clover, while Asta receives nothing. However, soon after, Yuno is attacked by a person named Lebuty, whose main purpose is to obtain Yuno's Grimoire. Asta tries to fight Lebuty, but he is outmatched. Though without hope and on the brink of defeat, he finds the strength to continue when he hears Yuno's voice. Unleashing his inner emotions in a rage, Asta receives a five-leaf clover Grimoire, a Black Clover giving him enough power to defeat Lebuty. A few days later, the two friends head out into the world, both seeking the same goal—to become the Wizard King!
